Detailed Procedure

1. Gather 10 people at my house.
2. Have one person do the Afuflex 3 Shoulder Rotation Test.
3. Measure how far apart their hands can go on the towel with the tape measure.
4. Have the person do the Hamstring Supine Stretch.
5. Take a picture, upload it to the computer, and print it out.
6. Using a black marker and a ruler, trace the angle the person’s two legs are in.
7. Measure the angle with a protractor.
8. Have the person lift two 3 pound weights, one in each hand, up and down for 3 minutes straight.
9. Repeat steps 2 and 3.
10. Have the person run laps for 3 minutes straight.
11. Repeat steps 4-7.
12. Record data in observation table.
13. Repeat steps 2 through 12 with 9 other people.
